1. Olsen twins
Mary-Kate and Ashley Olsen, started their career at the age of only six months, being chosen to play the role of little Michelle Tanner, in the successful series Full House. Thus, at an early age the Olsen twins entered the list of the richest stars in Hollywood.
As kids, the two were diagnosed with attention-deficit/hyperactivity disorder (in short ADHD) and underwent various treatments. Their mother was worried that the twins didn’t have a normal childhood, being surrounded by fame. However, she quickly changed her mind, after the producers from Full House proposed an increase in the twins’ salaries.
